JOSEPH JEAN PIERRE VIGROUX, OF PARIS, FRANCE.

FLEXIBLE AND ELASTIC DEVICE FORBEDS, LOUNGE-CHAIRS, ARM-CHAIRS, AND GARDEN-CHAIRS.

Application filed September 24, 1918.

To all whom it may concern:

Be it known that LJOSEPH JEAN PIERRE VIeRoUx, citizen of the French Republic, and resident of i Square 'Alboni, Paris, France, have invented Flexible and Elastic Devices for Beds, Lounge- Chairs, Arm- Chairs, and Garden-Chairs, of which the following is a full, clear, and exact description.

The present invention relates to a flexible and elastic device for camp beds, lounge chairs, arm chairs, garden chairs, and the like.

This flexible and elastic device has two transverse connecting rods which cross each other and are pivoted to the legs of the bed for example and to cross bars \which are themselves pivoted to each and to the legs of the bed; these cross bars are also connected to each other by springs which give the desired elasticity to the device; furthermore, the legs are connected to each other at their lower parts by a pivoted tie rod and at the upper part by the sacking of the bed.

This device constitutes a flexible and elastic element, and a certain number of similar elements arranged transversely at a certain distance from each other and suitably connected together form a folding chair or camp bed which is much more comfortable than the usual articles of this type.

This bed is specially recommended for invalids and wounded.

By wa of example, this invention will be describe hereafter with reference to the accompanying drawing in wvhich:

Figure 1 shows the device at rest in the transverse direction of its application.

Fig. 2 represents this device sidewise as applied to a bed.

Fig. 3 is a corresponding view to Fig. l but showing the device in operation.

It will be seen from the drawing the flexible device has, in a transverse direction, two legs a arranged vertically. To the upper parts of these legs a are pivoted at 5 two connecting rods 0 which cross each other freely and are pivoted likewise at their lower parts at b to cross bars d. These cross bars d in turn are pivoted at e to the legs a and to each other at f. The free end of each cross bar d is connected by a spring 9 to the other cross bar. Furthermore at the lower part Specification of Letters Patent.

Patented Feb. 25, 1919.

Serial No. 255,522.

the two legs a are connected by a tie rod it, while the ordinary sacking z connects these same feet at their upper parts.

The device hereinbefore described constitutes a flexible and elastic element which is used transversely in a bed, a lounge chair, an arm chair, a garden chair, etc.

In the case of a bed for example, three similar elementsare connected together by the two bearers j to .which is attached the sacking 13. Furthermore on the two sides of the bed, each leg is connected to the bearer above it by two hooks 70.

The two bearers j are let into recesses a made in the upper parts of the legs.

These bearers are in two parts connected at their centers by a pivot which allows them to be folded up.

The springs 9 have, at one end a hook g, and at the other end, a loop 9 which holds them to the ends of the cross bars d.

All the pivots may be formed by bolts or rivets.

The hooks 70 are pivoted at one end at 70' to the legs a, .while at the other end, these same hooks are hooked on to a convenient stop integral with the bearer.

The tie rods h are pivoted at the two ends 72 to the legs and at their centers k This device comprising the leg a, the connecting rods 0, the cross bars d, the tension springs g, of suitable strength and a tie rod h is perfectly balanced. Furthermore it is elastic in a symmetrical way with respect to its central pivoting f in the transverse direction, the high part of the two feet tending to slope inward at the same time as the two connecting rods 0 and the cross bars 03 straighten out and stretch the springs g.

This elastic flexion is shown in Fig. 3 of the drawing.

If a weight be supposed to be placed on the sacking 2', the central pivotal axis 7 of the cross bars Q! will descend at the'same time as the constituent parts such as the connecting rods 0 assume the positions indicated in this figure. If the weight be represented by a erson placed upon the bed, the sacking i will take the shape of this person and this elastic bed will insure to this same person good accommodation in a collapsible and flexible bed without the aid of a mattress.

Similar elements arranged crosswise and connected by bearers of a suitable kind will enter into the construction of lounge chairs, etc.

The folding up of a bed constructed from elements formed by this device is an extremely simple operation since it suflices to remove the bearers and the sacking attached thereto after having disconnected the various retaining hooks.

The forms, details, accessories, materials and dimensions of this elastic device may it should be understood vary .Without in any Way altering thereby the principle of the invention.

I claim A flexible and elastic device for camp beds, lounge chairs, arm chairs, garden chairs, and the like arranged transversely and constitut- 1ng an element, the said device comprisinga pair of legs, a pair of cross bars pivoted both to said legs and to each other, two connecting rods crossing each other freely, pivoted at their upper parts to the legs and at their lower parts to the cross bars, tension springs connecting said cross bars on both sides of their common pivot, a pair of tie rods piv- JOSEPH JEAN PIERRE VIGROUX.
